To LIZ whom. t may concern Be it known that l. @Tis A.. Fnnnzn? a citizen ci the ilnited States, residinga at loliet, in the county ot Viill and State oi: illinois.:

t5 have invented certain new and useful lin provements in Combination Pipe Fittings and Traps; and l do hereby declare the tollowing' to be a full. clear, and exact description of the invention7 such as will enable l others skilled. inY the art to which it appertains to make and use the same.

The present invention relates to pipe ittinge7 and aims to provide a novelpipe titting for the drain pipe of a dwelling or other building', havin;- combined therewith a's an integral unit, a trap provided with one or more inlet portions for the connec tion of branch pipes, and preventing the escape of gases from the drain pipe back through the branch pipes.

The invention resides in the novel combination of a pipe section and trap comprising an integral unit and providing for several advantages as hereinafter set forth. With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention residesin the construction and arrangement of parts, as hereinafter described andclairned. it being understoodthat changes can be made within the scope of what is claimed. without departing` from the spirit of the invention.

The invention is illustrated in the accompanyingidrawings. wherein- `Figure l is a 'plan view of one form of combination pipe fittingand trap embodying the improvements.

iieferrinr;` to Figs. l. 2, 3 and Ll, the pipe fitting comprises the pipe section or tubular body having' the faucet or bell ends 2lA and 22 to receive the spigot ends ot the pipe sections 23 4of the drain pipe o1 a building, which usually extends within or adjacent to one of the walls of the building to receive the drainage from the several floors of the building. The ends of the pipe section or body 20 vmay have screwthread or other means of connect-ion instead of the faucet and spigot connections shown. The body ory pipe section 20 has cast as an integral unit therewithl a trap chamber 24 located at one side of the body oripipe section 20, the wall of the pipe section 2O at said side forming a partition between the passage of the pipe section and the interior of the trap chamber.` This wail Vor partition has an opening 25 establishing communication between the pipey section and chamber, andsa'id chamber will hold ,water in the lower portion thereof upto the level oi' the lower edge of the openingr 25. The chamber 24is provided therein with a parti-V tion 26 integral with opposite side walls ot the chamber, vwith its lowerend extending downwardly past the horizontal plane or level ofthe lower edge oi" the opening 25, while the upper end portion of the partition extends at an angle Varmy fromy the .the chamber opposite to said openingtvas lclearly seen in Fig. 2.

The casting is formed with van inclined `passage 27 extending through the wall'o'f the chamber 24 aty one side. and thelower end portion of the wall of said passage is v`united with the partition 26, whereby the *opening 25 and merges into the wall of y may be screw threaded, as at 28, or formed f with a faucet or other portion for the connection of the branch pipe leading from the fixtures. By having the passage 27 terminating substantially flush with the upper end of the pipe section 20. this provides for the convenient connection or L pipe with the trap. rEhe uppe en t chamber 2i is also preferably ilush with t upper end ot the pipe section, whereby t casting can be substantially iiush with t floor if desired, h thetop of the chant.- ber 24 and upper end portion ot the pas-- sagre 2'? exposed cr readily accessible.

rEhe water which drains down throng1 passage 27 must pass under n 2G to tiow through the opening drain pipe, so that `the water in portion ot the treo cnniber water seal to prevent the reversely troni the drain pi*i c trap into the passage 27.

rEhe top of the trap chamber has an opening; 29 above the partition normally closed by the screw plug 30, whereby access can be had into the trap when the plug is removed, or the plug can be reinoved and the opening 29 used 'for the connection of another branch pipe to discharge into the trap chainber betweenthe partition 26 and opening 25 without the water having to pass under the partition. The opening 29 and plug 30 being located at the top ot the trap are readily accessible.

The trap chamber 2li has at its bottoin a drain plug 3l which can be removed 'for draininr or cleaning out the trap.

The pipe section 2G may have ineans for the connection ot one or more other branch pipes, and, as shown, the pipe section 20 has a branch 32 for the connection of a branch pipe. This branch, or several or them, can be of dierent formations, to provide Y- connections, elbow connections, Tconnec tions, and the like.

Fig. 5 shows thepartition 26a extending upwardly and united with the top of the trap chamber 24R, said chainber having an opening 29a at that side of the partition opposite to the, pipe section 20a, with the top of the trap chamber extending on an inoline to the upper portion of the opening 29a. The passage 27*L is shown at the near side of the pipe section and trap chamber, and there is illustrated a further niodiiication by the provision ot a boss 32EL integral with the lower end or bottoni of the chainber 24C* and corresponding side ot the pipe section 2Oa and having an opening 32 tor the connection of a branch pipe to discharge directly into the drain pipe under the trap. Wherever screw threaded connections are shown, it will be understood that slip, faucet, and spigot, and other connections can be used, and vice versa.

Fig. 6 shows the pipe section 2Gb, trap chamber 24h, opening 25", partition 265, opening 29h and plugs 30h and 51b substantially the saine as in Figs, 1 4. There is also shown an opening 27 in the wall of 4the trap chainber at that side or' the parti- 26b opposite to the opening 25, for the oction ot a branch pipe, and the wall of irainber aise an opening 32b 1Ane connection ot a branch pipe between 26h opening 25".

er is shown as havingl the drain plug Figs, 9 anc 1G show fixture having two Thus, the trap chambers 24B are cast with the pipe section 20e at the opsides thereof, and said pipe section aiicets 21e 225 at the upper and 1iowe ones thereof, or other ineens 'for the connection of the companion pipe sections. There is opening 25 between each trap chamber the passage ot the pipe section 20G, the same as in the other constructions, and each trap chamber has a partition 26 therein.

The passages 2?@ which open through the partitions 25e, diverge downwardlyr at one side ot the pipe section 2()e from a common or terminal portion 28 to which abranch pipe or pipes can be connected, said portion 28e beingr substantially iusa with the upper end of the pipe section 20. The

ction Aawayw rom the pipe section 2Oe the connection of other branch pipea or said openings can be plugged closed Each trap chamber has 'a drain plus` 81B.

il shows another type of double tint-.rse` the trap chambers 24' being teeral with the opposite sides of the 202 and the traps are of the shown in Fig. 8, exceptingl that the bosses 32e are provided between the lower eras of the trap chambers and pipe section having the openings 32 for the conneet-ion ot branch pipes to discharge directly into the pipe section. The openings 2E)t entend upwardly at an angle from the openings 25, and the trap chambers have inlet openings 27f tor the connection of branch pipes at those sides of the partitions 26f opposite to the openings 25f.

Having thus described the invention, what is claimed as new is l. A combination pipe iitting and trap comprising a vertical pipe section, a trap Chamber at one side thereof and integral therewith, said pipe section and chamber having a partition between them provided with an opening, said chamber having a partition therein extending downwardly helow the horizontal plane of the lower edge of said oyeninff and a assa e o enin through said partition into said chamber at that side of the partition opposite to said opening, said passage extending upwardly at one side of said pipe section.

2. A combination pipe fitting and trap comprising a vertical pipe section, a trap chamber at one side `thereof and integral therewith, said pipe section and chamber having a partition between them provided with an opening, the chamber having a par- .said opening, and a passage leading through the wall of said chamber and opening through said partition to communicate with said chamber at that side of the partition opposite to said opening, said 'passage extending upwardly at one side of said pipe section for the connectionfof a branch pipe, with the upper ends of said passage and pipe section substantially iush.

In testimony whereof have signed my name to this specification in the presence of two subscribing witnesses.
